AAC Conductor, All Aluminium Conductor (JIS C 3109)
AAC conductor is widely used in power transmission lines with various voltage levels.
Since they have such good characteristics as simple structure, convenient installation and maintenance, low cost for the line, large transmission capacity and are also suitable for laying across rivers and valleys where special geographical teatures exist.
(1) all aluminium conductor (AAC)
(2) all aluminimum alloy conductor(AAAC)
(3) aluminum conductor steel reinforced (ACSR)
(4) anti-corrosion type ACSR
(5) aluminimum conductor aluminimum clad steel reinforced(ACSR/AW)
(6)rear earth aluminimum conductor steel reinforced(ACSR/RE)
(7)aluminimum conductor aluminimum alloy reinforced(ACAR)
2. Elative manufacturing standards:
(1). IEC 61089: Round wire concentric lay overhead electrical stranded conductors
(2). DIN 48 201-5: All Aluminium Conductors
(3). BS 215-1: Aluminium strander conductors
(4). ASTM B 231: Stranded Specification for Concentric-Lay-Stranded Aluminium 1350 Conductors
(5). AS 1531: Conductors-Bare overhead-Aluminium and aluminium alloy
(6). JIS C 3109
Used as bare overhead transmission cable and as primary and secondary distribution cable. ACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity.
Aluminum alloy 1350-H-19 wires. Corrosion protection is available through the application of grease to the corrosion or infusion of the complete cable with grease.
Resistance is calculated using ASTM standard increments of stranding and metal conductivity of 61.2% IACS for EC (1350) and 8% IACS for steel. AC (60Hz) resistance includes current dependent hysteresis loss factor for 1 and 3 layer constructions.
Current ratings are based on 75oC conductor temperature, 25oC ambient, 2ft/s wind, 96/watts/sq. Ft sun, 0.5 coefficients of emissivity and absorption.
